Hey have a problem by using a foreach loop of an object which is extending a Map. I try to setup my mocking like this
val tableMock = mockk<MyTable>(relaxed = true, name = "My table Mock")
val tableEntryMock = mockk<MyEntry>(relaxed = true, name = "My entry Mock")
every { tableMock[any()] } returns tableEntryMockBut in my foreach, where I'm iteration over MyTable nothing happen because its size is 0, obviously. So I try:
val tableMock = mockk<MyTable>(relaxed = true, name = "My table Mock")
val tableEntryMock = mockk<MyEntry>(relaxed = true, name = "My entry Mock")
val expectedMap = mutableMapOf<Int, MyEntry>(1 to tableEntryMock)
every { tableMock.iterator() } answers expectedMap.iterator()But the precompiler has a problem with my 'answers' :None of the following functions can be called with the arguments supplied.
answers(Answer<MutableIterator<MutableMap.MutableEntry<Int, MyTable>>>) defined in io.mockk.MockKStubScope
answers(MockKAnswerScope<MutableIterator<MutableMap.MutableEntry<Int, MyTable>>, MutableIterator<MutableMap.MutableEntry<Int, MyTable>>>.(Call) → MutableIterator<MutableMap.MutableEntry<Int, MyTable>>) defined in io.mockk.MockKStubScope
answerstakes a block, not a value
you should be doingevery { tableMock.iterator() } returns expectedMap.iterator()or
every { tableMock.iterator() } answers { expectedMap.iterator() }
Thanks to @Raibaz this doesn't solves the problem fully, but brings me one step forward (was using 'answers' wrong). Problem is a different type of the Iterators.
I'm trying to verify that a call was made. I'm using
verify (exactly =1) and there's no problem when passing in a normal string as an argument, but it's saying was not called when I use a list of strings as an argument. I've tried every combination of eq and similar that I can think of, but it's still insisting that the function hasn't been called when it definitely has. I thought it could be a reference vs value thing, but the eq thing negates that as an option. Any ideas?
was not called.
Hi guys, i'm trying to deal with chained calls verify, but it's not work :(
here is my example, could you pls take a look? (sorry for bad english)
@Test
fun testChainedCallVerify() {
val mock = mockk<RedisTemplate<String, String>>() {
every { boundValueOps(match { it.startsWith("sys_") }) } returns mockk() {
every { get() } returns "0"
}
every { boundValueOps(match { it.startsWith("aux_") }) } returns mockk() {
every { get() } returns System.currentTimeMillis().toString()
}
}
println(mock.boundValueOps("sys_1").get())
println(mock.boundValueOps("aux_2").get())
verify { mock.boundValueOps(eq("sys_1")).get() } //without get() this verify doesnt fails
verify { mock.boundValueOps(eq("aux_2")).get() } //without get() this verify doesnt fails
/*val boundOpsMock = mock.boundValueOps("sys_1")
verify { boundOpsMock.get() } //but it's work, except confirmVerified*/
confirmVerified(mock)
}and i getting exception java.lang.AssertionError: Verification failed: call 2 of 2: BoundValueOperations(child of #19#23).get()) was not called
io.mockk.MockKException: Missing calls inside verify { ... } block error on Android API level 21 where the test passes correctly on Android API level 30. Error is reproduced both on my Jenkins CI and my computer.

Hi everyone, I am struggling with testing objects implementing abstract classes:
abstract class Base(open val lib: Lib) {
abstract fun Lib.doTheThing()
fun meaningfulStep() = lib.doTheThing()
}
class SomeImpl(lib: Lib) : Base(lib = lib) {
override fun Lib.doTheThing() {
lib.doSomeThing()
}
}
class AnotherImpl(lib: Lib) : Base(lib = lib) {
override fun Lib.doTheThing() = lib.doAnotherThing()
}
class Lib {
fun doSomeThing() = println("I just executed some awesome thing!")
fun doAnotherThing() = println("I just executed another awesome thing!")
}This is how I would use this example in runtime and it works as expected:
val lib = Lib()
SomeImpl(lib).meaningfulStep()
AnotherImpl(lib).meaningfulStep()But tests are failing:
@Test
fun calling_some_thing() {
// given
val mockLib = mockk<Lib>()
val impl = spyk(SomeImpl(mockLib))
// when
impl.meaningfulStep()
// then
verify {
mockLib.doSomeThing()
}
}
@Test
fun calling_another_thing() {
// given
val mockLib = mockk<Lib>()
val impl = spyk(AnotherImpl(mockLib))
// when
impl.meaningfulStep()
// then
verify {
mockLib.doAnotherThing()
}
}
How do we set mock responses for Function literals with receiver?
Basic example:
interface ThingDoer {
fun doThing(): String
}
class DoerProxy {
private val doer = object : ThingDoer {
override fun doThing(): String {
return "did a thing"
}
}
fun <T> doProxyThing(func: ThingDoer.() -> T): T {
return func(doer)
}
}
class DoerUser(private val proxy: DoerProxy) {
fun useThing(): String {
return proxy.doProxyThing { this.doThing() }
}
}
class DoerUserTest {
@Test
fun testUseThing() {
val expected = "something"
val mockProxy: DoerProxy = mockk()
every { mockProxy.doProxyThing { doThing() } } returns expected
val doerUser = DoerUser(mockProxy)
val actual = doerUser.useThing()
assertEquals(expected, actual)
}
}Gets me an error: io.mockk.MockKException: no answer found for: DoerProxy(#1).doProxyThing(lambda {})

Hello, I'm having some trouble mocking a constructor, I'm not even sure if this is possible but I was hoping to get something like this going
class Foo(val foo: Int) {}
class FooTest {
@MockK
lateinit var foo: Foo
@BeforeTest
fun setup() {
MockKAnnotations.init(this)
mockkConstructor(Foo::class)
}
@Test
fun fooTest {
every { Foo(any()) } returns this.foo
Foo(0)
verify { Foo(withArgs { assertEquals(it, 0) }) }
}
}Do you guys have any idea how I could get this behaviour? Thanks in advance.
Here is my code @Test
funtest 1`() {
var mockCar = mockk<Car>()
every { mockCar.changState(any()) } just runs
every { mockCar.setState(any()) } just runs
mockCar.changState(10)
verify(exactly = 1) { mockCar.changState(any()) }
verify { mockCar.setState(any()) }`
java.lang.AssertionError: Verification failed: call 1 of 1: Car(#2).setState(any())) was not called.
Calls to same mock:
1) Car(#2).changState(10)class State {
var state: Int = 10
}
class Car {
//var state:State = State()
fun changState(data: Int = 1) {
setState(data)
}
fun setState(data: Int = 0) {
//state.state = data
}
}
Does any one have idea, how to set private value for any collection object?
class CustInfo {
private var customerInfoList: MutableList<CustomerInfo> = mutableListOf()
fun updateCustomerInfoList(list: MutableList<CustomerInfo>){
customerInfoList = list
}
fun clearItems() {
if(customerInfoList.isEmpty()){
customerInfoList.clear()
}
}}

Hello! I have a problem with kotlin 1.5.21, 1.5.30, and mocking observers from android lifecycle 2.3.1 with mockk.
It works on kotlin 1.4.32
How to reproduce:
val dialogObserver: Observer<Unit> = mockk()
every { dialogObserver.onChanged(any()) }.returns(Unit)
Log:
